you can also convert a stereo file to mono (and visa-versa) using an option in the Edit menu. For the really adventurous (apply with caution) there are audio limiting and compression options along with dozens of other built-in effects. It is VST compatible, includes many audio enhancement options – such as noise reduction – along with many effects podcasters will not need, such as reverb, echo, chorus and flanger etc. Ocenaudio works on all platforms (Windows, Mac, Linux), offers real time effects – meaning that during playback – as you alter EQ (for example) you will hear the changes as you move the EQ sliders. Users can highlight small sections - such as where breath noises may appear – and lower the volume using a volume slider that appears right where the edit is taking place, there's a highlight and delete option of course, you can highlight all and normalise. However, the app does offer multiple undos if you want to take your edits back a few steps. Thereby keeping a back-up of the original well out of harm's way. So the trick is to record, Save, and then Save As with a new name (V2 for example). That means, if you record something with it and start cutting and editing, you will be working with the original source file. The app is regularly updated, almost every month I reckon, and will serve most people's needs – so long as you don't need multi-track recording and know the difference between a destructive audio editor and a non-destructive one.

I've recommended Ocenaudio to many friends who were looking for a simple no-frills way to record their voice overs, podcasts, and professional radio shows. It's totally free, reliable, and as solid as any audio app can be.

There's an audio recording and editing app I've been using on and off for a few years now that's ideal for recording podcasts and radio shows.
